We present the design and core functions of the framework and apply it to various NIST LWC authenticated encryption with associated data (AEAD) ciphers. Altogether, we evaluate the speed of 213 submitted algorithm vari-ants on four different microcontroller units (MCUs), including 32 bit ARM and 8 bit AVR architectures. To allow a more meaningful comparison, we also conduct code size tests on all four boards and RAM utilization tests on one test platform.

Now and in the near future, penetration tests in the area of automotive security will still require tools for CAN media access. More and more open source automotive penetration tools and frameworks are presented by researchers on various conferences, all with different properties in terms of usability, features and supported use-cases. Choosing a proper tool for security investigations in automotive network poses a challenge, since lots of different solutions are available. This paper compares currently available CAN media access solutions and gives advice on competitive hard-and software tools for automotive penetration testing.

Technologies like Bluetooth and Internet-connected services found their way into the vehicle industry. The secure implementation of these functions presents a great challenge for the manufacturers because products originating from the consumer industry can often not be easily transferred to the safety-sensitive traffic environment due to security concerns. However, common automotive interfaces like the diagnostics port are now also used to implement new services into the car. With dongles designed to read out certain vehicle data and transfer it to the Internet via the cellular network, the owner can access information about gas consumption or vehicle location through a mobile phone app, even when he is away from the car. This paper wants to emphasize new threats that appear due to the ongoing interconnection in modern cars by discussing the security of the diagnostics interface in combination with the use of an Internet-connected dongle. Potential attack vectors, as well as proof-of-concept exploits will be shown and the implications of security breaches on the safe state of the vehicle will be investigated.
